I've finally managed to make some measurements on the adapter card regarding power. At the soldering where the wires from the molex are connected there is indeed both 5 & 12V. I haven't successfully measured the PCI pins directly though, but they should be up the specs if there isn't some internal

The power issue did cross my mind after some more research. Maybe that would explain why the card is registering correctly but not returning any tuned data. I haven't found any detailed requirement specs for the tv card but I assume that the tuner/demodulator could consume a fair amount of power. H

last, but not least, that i totally forgot - on my tests with audio card PEX 8111/8112 adapter is stuttering to transfer 8 channel, 192 kHz, 24-bit audio, which is very small data rate comparing to DVB data - i'm not sure though, it's because of increased latency or PEX 8111/8112 adapter can't hand

oh, i have just noticed your DVB card is for Cable and not for Satellite, but still it may use 12V PCI interface pins for something else and not exactly for LNB power as i thought assuming it's DVB-S/S2 DVB card. On Tue, Feb 15, 2011 at 10:18 AM, Konstantin Dimitrov wrote: > hi, does your DVB car

hi, does your DVB card can get signal lock when it's inserted into the PCI-to-PCIE adapter, because as far as i know most PCI-to-PCIE adapters based on PEX 8111/8112 don't provide power to 12V pins of the PCI interface, which probably all PCI DVB card use for LNB power. so, what i would check if i

Hello, This card (technisat cablestar hd 2 dvb-c) works fine when plugged into a native PCI slot. When I try it with a PCI-adapter I intend to use in mITX-builds there doesn't seem to be any data coming in through the tuner. The adapter is a transparent bridge (with a PEX 8112 chip) that goes into
